I should first confirm if the movie exists. "Yu Pui Tsuen III" sounds like a Hong Kong movie, perhaps a crime thriller. The 1996 release year makes sense for Hong Kong films. The 18 rating in China would indicate violent or adult themes. The BluRay aspect suggests maybe a higher-quality release, but the file size being 950MB is unusually small for a standard BluRay, which typically is much larger. Maybe it's a converted version or a rip.
